The 1959 NAIA men's basketball tournament was held in March at Municipal Auditorium in Kansas City, Missouri. The 22nd annual NAIA basketball tournament featured 32 teams playing in a single-elimination format.[1] The 1959 Tournament is the first tournament to use the 16-seed system, which was used until the 2015.
The championship game again featured Tennessee State University. The Tigers defeated the Lutes of Pacific Lutheran University. It would be the first time any school would win three consecutive tournaments; a feat only repeated once, by Kentucky State, in 1970, 1971, and 1972. It was also the first tournament that didn't feature an upset in the championship game and first time a "true" number 1 seed won the tournament since seeding began in 1957.
Many of the records set by the 1959 tournament have been broken, and many of the awards were established much later:
The third-place game featured the losing teams from the national semifinalist to determine 3rd and 4th places in the tournament. This game was played until 1988.
